Abstract
A resin molded body includes: a polyolefin element formed of polyolefin, including a crystalline region and an amorphous region; and a hydrophilic copolymer contained in at least part of a surface of the polyolefin element, the hydrophilic copolymer including a copolymer of 2-methacryloyloxyethyl phosphorylcholine (MPC) of 45% or greater on a mole fraction basis and at least one other monomer. In the resin molded body, the MPC polymer is immersed through the surface by applying heat treatment.
Claims14
A resin molded body, comprising:
- a polyolefin element formed of polyolefin, comprising a crystalline region and an amorphous region;
- and
- a hydrophilic copolymer contained in at least part of a surface of the polyolefin element and in part of the amorphous region that is located below the surface,
- the hydrophilic copolymer comprising a copolymer of 2-methacryloyloxyethyl phosphorylcholine of 45% or greater on a mole fraction basis, and at least one other monomer.
A method for producing a resin molded body, the method comprising:
- preparing a polyolefin element formed of polyolefin, the polyolefin element comprising a crystalline region and an amorphous region;
- forming a coating of a hydrophilic copolymer on at least part of a surface of the polyolefin element, the hydrophilic copolymer comprising a copolymer of 2-methacryloyloxyethyl phosphorylcholine of 45% or greater on a mole fraction basis, and at least one other monomer;
- and
- applying heat treatment to the polyolefin element on which the coating of the hydrophilic copolymer is formed,
- wherein by applying the heat treatment, the coating of the hydrophilic copolymer is immersed through the surface of the polyolefin element into part of the amorphous region located below the surface.
